Question for the collective.Upon rebuilding my lower end with new main ball bearing (timing side) I have about .024 of crankshaft end play (float). Workshop manual allows up to .017, should this be addressed? How?

If you believe that,you'll also believe that you don't need any bearing shoulders in the cases to stop the bearings walking out either side of the engine when it is hot and loaded.Fact is you do need these bearing shoulders.If you can't see daylight between the top of the outer race and the case,when the engine is hot and under load,its bloody close to that.Put your shims on the mainshafts,between the bearing and the crank web, where they are most likely to centralize the conrods in the cylinders.Leave at least 0.003" float(end clearance for the rollers on the drive-side bearing);yes ,I know 0.003"-0.017".THEN tighten up the crank to the timing-side bearing.Would every body be happy with that?I reckon I'd be happy with it,especially if the rods were pretty central,and the drive-side rollers had 0.003" clearance,minimum, and not too much more.
